Amides of glucuronic, galacturonic, and mannuronic acids

Journal of Research of the National Bureau of Standards, 1948
Heretofore the amides of glucuronic, galacturonic, and mannuronic acid were not known, and methods were not available for their preparation. It has now been found possible to obtain the amides of uronic acids from the corresponding 1-amino-uronamides by selective hydrolysis of the glycosylamino group.

Liquid Chromatography Coupled With High‐Resolution Mass Spectrometry Profiling of Metabolites in Cassia alata Flower Extracts and Their DPPH Free Radical Scavenging Activity

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Cassia alata flowers remain phytochemically under‐characterized relative to the leaves. However, floral tissues can harbour distinct and, in some species, more abundant phenolic and flavonoid profiles, representing an unexploited source of antioxidant phytochemicals with potential functional‐food and nutraceutical relevance. Also, Cassia alata

Multi‐Analytical Characterization and Taxonomic Distinction of Australian Plant Exudates

Analytical Science Advances, Volume 7, Issue 2, December 2026.
The distinct physicochemical properties of plant exudates have led to millennia of use as medicines, food additives, and adhesives. Chemical analysis of exudates sheds new light on past technologies, artifact origins, and molecular structure‐function relations.

Dielectric Relaxation, Water Sorption Thermodynamics, and Humidity‐Sensing Mechanisms of Compressed Ulva Biomass Pellets

Applied Research, Volume 5, Issue 6, December 2026.
This study investigates the moisture sorption thermodynamics, dielectric relaxation behavior, and humidity‐sensing performance of compressed Ulva biomass pellets. The findings demonstrate that sustainable macroalgal pellets provide low hysteresis (~1.63%) and wide‐range sensitivity for green environmental diagnostics.

Metabolic pathway analysis of the biodegradation of cellulose by Bacillus velezensis

Heliyon
A green strategy that using Bacillus velezensis to degrade cellulose in bamboo forest waste was demonstrated. The cultivation conditions of microorganism, identified as Bacillus velezensis by 16S rDNA, were optimized by response surface methodology (RSM).

Isolation, Structural Elucidation, and Anti‐Melanogenic Activity of a Novel Pectic Polysaccharide From Alhagi camelorum Fisch

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Polysaccharide extraction from Alhagi camelorum Fisch. was optimized, yielding ACP‐II‐1, a novel GalA‐rich, HG‐dominant pectin (26.145 kDa) containing branched RG‐I domains. ACP‐II‐1 reduced melanogenesis in forskolin‐stimulated B16F10 cells and a zebrafish model.

Medjool Date Seed Polysaccharides Attenuate DSS‐Induced Colitis and Associated Hepatic Oxidative Injury in Mice, Accompanied by Gut Microbiota Alterations

Food Frontiers, Volume 7, Issue 6, November 2026.
Medjool date seeds were dried, milled, and extracted (80°C, 180 min), followed by centrifugation (1000 rpm, 15 min) and BCA analysis to obtain the polysaccharide fraction (MDSP), which was characterized by TEM, FTIR, XPS, NMR, UV‐Vis, and TGA. In Balb/c mice with DSS‐induced colitis (2.25% DSS, Day 1.15), oral administration of MDSP‐H (300 mg/Kg ...
